However. when the tiltable knob is rocked to lock the slide to the fastener-applying arm the longitudinal component of the arcuate movement of the latter is translated through the interlocking means on the slide and anvil into a sliding movement of the latter to aline a different set of clinching means with the fastener being driven. a

In the accompanying drawings the invention is illustrated as applied to an implement for driving and clinching U-shaped staples, but it is to be understood that it is adapted for use with various devices for driving and clinching other forms of fasteners. As herein illustrated, the implement comprises a rectangular base 2 having a top plate 3 and a depending marginal flange 4. The top plate 3 and depending flange 4 of the base 2 are cut away at the forward end to provide a recess 5 therein, see Fig. 6, and adjacent the rearward end of the base the top plate 3 is provided with a pair of spaced slots 6. A U- shaped bracket 1 is mounted on the base 2 with its web portion 8 'in abutting engagement with the bottom face of the top plate 3 and its side flanges projecting upwardly through the slots 6 to provide spaced ears 9. As herein illustrated 'thebracket 'l is attached to the base 2 'by means of a rivet ll! extending through its web portion 8 and the top plate 3, but it may be secured in place by any other suitable means such as Welding or the like. The upwardly-extending ears 9 on the bracket 1 are pierced with alined holes for receiving the opposite ends of a pivot pin '|2.

In accordance with the present invention an anvil-plate 2B is mounted on the top plate 3 of the base 2 to slidelongitudinally thereof. The anvil-plate 20 is of generally rectangular form having a depending beveled lip 2| at its forward end extending into the recess 5 in the base 2 and a reduced portion 22 at its rearward end adapted to fit closely between the spaced ears 9, the side 'edges of the recess and the inside faces of the ears serving to guide the anvil-plate during its sliding movement on the base. Adjacent its forward end the anvil-plate 20 is provided with separate sets of clincher-grooves 23 and 24 formed therein and arranged in longitudinallyspaced relationship. The clincher-grooves 23 are adapted to deflectthe legs of a staple inwardly toward each other to form a permanent stitch as illustrated in Fig. 8; while the clincher-grooves 24 are adapted to deflect the legs of the staple outwardly away from each other to form a temporary or pin-stitch as shown in-Fig. 9. The anvil- 'ment of the anvil-plate 20. 'Preferably, the

tongues 3|] and 3| are formed in the top plate 3 of the base 2 by punching out an E-shaped piece. The tongues and 3| may be bent either forwardly or rearwardly by any suitable tool to initially adjust the relationship of the anvil-plate 20 with respect to the base 2. The anvil-plate 2D is yieldingly held in its forward position of adjustment by means of an S-shaped spring 32 tensioned between the depending stud 26 and a stud 33 secured on the under side of the top plate 3 of the base 2. Preferably, a cover-plate 34 is provided between the spring 32 and the bottom of the top plate 3 of the base 2 as shown in Fig. 4 and indicated by dash lines in Fig. 6.

The stapling arm comprises a staple-maga-- zine 4| and an operating lever 42 constituting a cover in which the magazine is adapted to be nested, the magazine and lever being mounted to rock on the common pivot-pin l2. The magazine 4| is of channel-shape in cross-section, comprising a bottom wall 43 and upwardly-extending side walls 44 folded inwardly at their upper edges to provide retaining flanges 45 for the staples s.

The rearward end of the magazine 4| is positioned between the ears 9 on the base 2 and its side walls 44 are pierced to provide alined holes through which the pivot-pin l2 extends. Adjacent the forward end of the magazine 4| the side walls 44 extend upwardly and forwardly to provide overhanging stanchions 46; while adjacent its rearward end are ears 4! folded upwardly from the-retaining flanges 45. Rails 48 are mounted on the bottom wall 43 of the magazine 4| in spaced relation to its side walls 44 to provide a core for supporting U-shaped staples s straddled thereacross. The rails 48 forming the core project forwardly beyond the magazine 4| to underlie the overhanging stanchions 46 and are provided with latching lugs 49 adjacent their lower edges. v

The forward end of the magazine 4| is closed by a U-shaped gate having a front wall 55 which cooperates with .the end of the core to provide a throat 51 therebetween and side walls 58 which overlie the sides of the core with notches 59 formed therein for cooperation with the latching lugs 49. The gate 55 is pivotally mounted'on the magazine 4| by means of a pin 6|] which extends transversely through alined holes in its side walls 58 and oval slots 5| in the stanchions 46. Thus the gate 55 may pivot on the pin 50 to open the magazine but is normally held in its closed position by the engagement of I the notches 59 in its side walls 58 with the latching lugs 49 on the forwardly-projecting ends of the rails 48.

A' blade-like staple-driver 65' mounted to reciprocate in the throat 51 has a slotted opening 65 adjacent its upper end. An actuating lever 61 for thestaple-driver 65 is pivotally mounted adjacent its rearward end on a pin 68 extending between the upwardly-extending ears 4? on the magazine 4|. The lever 51 is normally inclined upwardly from its pivot with its forward end proje cting through the slotted opening 66 in the staple-driver 65. A coiled hairpin spring 69 acting between the pivot-pin for the gate 55 and -the bottom side of the lever 61 yieldingly holds the latter in its raised position with the driver raised above the end of the staple-core, the upward movement of the lever being limited by the engagement of its curved rearward end ill with the top of the magazine 4|. The spring 69 also functions to maintain the gate 55 closedyr against the end of the magazine. A pusher is-mounted in straddled relationship on the rails 48 of the staple-core and is adapted to be yieldingly advanced to feed the staples 8 into the throat. 51 by means of a coiled spring 12, see Fig.

4. The spring 12 has one end attached to the pusher 1| and extends forwardly between the rails 48, being looped around a transverse stud 13 supported between the rails and then rearwardly with its opposite end attached to a lug trated in Fig. 1.

I z2; i ,'1-* .14son thebottom wall '43 .of the magazine 4|.

portion 18 at the rearward end of the spring be-' ing adapted to engage'thebase to limit the upward movement of the arm.

A'slide 88 mounted on the magazine M is' of generally rectangular form with slots 82 and 83 adjacent its opposite ends. The'rearwa'rd end ofthe slide '88 is mounted on the end of the pivot-pin 68 and its forward end on a stud 8| supported by the stanchions 46, the pin and stud :being engaged in the slots-82 and 83 in the slide. .Thus the slide-88 is free. tomove longitudinally of the magazine 4|, being. guided by-the stud BI and pivot-pin 68 on which it is mounted. An 'arm- 84 depends from the slide 88 at its rearward "end and is arranged for engagement with the upwardly-extendingflange on the sliding anvil 28. The upper edge of theslide 88 is recessed intermediate its ends to provide a locking shoulder 85.

At the side of the slide 88 is a locking lever 86 p-ivotally mounted'on-the-pivot-pin 68 between the actuating lever 61 and the ear 41, see Figs. '5 and 7. As herein illustrated the pin 68' extends through a central bearihgportio-n of the lever 86 which abutsfthe side of the lever 61 while the "offset end portions of the lever 86 bear against the inside face of the slide 88. The forward end portion of the locking lever 86'has an outwardly-extending lateral lug 81 overlying the top edge of the slide 88rand an inwardly-extendinglug '88 projecting between its end portion and the actuating lever 61. A helical spring "88 is connected between an ear '98 at the upper edge of the slide 88 and anear 9| at the "lower edge of the locking lever 86. Thusthe spring=89 normally functions to yieldingly retain the slide '88 retracted to its rearwardposition and'the locking lever 86 rocked to its inoperative position as illus- The spring 88 has considerably less resistance'than the spring 32; previously described, to adapt the slide 88"to norm'ally move with 'resp'ect to the anvil 28. The locking lever 86, howeven is adapted to be rocked to engage its lug 81 with the locking shoulder 85 on the slide 88 to hold the latter against movement relatively of the anvil 2 8.

The operating lever42 is of inverted channelsha'pe in cr'oss sec'tion having a top 'wall 95, de-

pending side walls 96 adapted to "embrace'the -'-sides of the magazine and arront'wau 91 "adapted to overhang the forward end of'the magazine. "As illustrated in Fig. 5, the rearward portions of the side walls 96 'are'offset outwardly 'to adapt them 'to fit closely between the up- "standing ears 9 on the base 2 and are provided with inwardly-projectingbosses 98 engaging the sides of the magazine to hold it centrally thereof. The bosses 98 are pierced with-"aline'd holes f through which the pin I2 extends to pivotauy mount the lever 42 on the base 2. I

In accordance with the present invention a selective control element is mounted on 'the stapling arm to adatiit it to efi'ct'i'elativ'e afdjustment between thearin and'theslidableanvil 28 to aliiie "a"staple "beingdrive'n with a particular 'set o-f the clincher-grooves 23 or 84. In the nema; illustrated embodiment-of the invention the selective-control element is "in the form of a qaresseriknobzimo rockably mounted on the lever I8 6 attached thereto. 'of the control arm I06 overlies the inwardlytrated in Fig. 1.

4'2 yadjacentits forward end. Th'ek-nob I88 has a plate lfll attached to' its bottom with ears I82 .extendingatright-angles thereto. The ears I82 project downwardlythrough anopening I83 in the top wall I 95;;of the lever. 42 and are pierced with alined holes adjacent'their free ends.

y this means the knob I88 is pivotally mounted on a-pin I84 ;extending--between the side walls 96 of the lever". and through the alined holes in Fig. 2 -to that illustrated in Fig. 3, and vice versa. One of .the tears I82,has a rearward extension I05 with a rearwardly-extending control arm The rearward or free end extending lateral lug 88 on the locking lever 86. Thus, when manual pressure is applied to the knob I88 forwardyof the pivot-pin I84 to operate the implement the knob and attached control arm I86 will be rocked on its pivot toposition the free end of the control arm above the lug 88 on the locking lever 86. The slide 88 is with the locking shoulder 85 on the slide 88. An

upstanding ear I81 at the forward end of the actuating lever 61 is positioned between the depending ears Won the knob I88 and has a'slot I88 therein through which thepivot-pin I84 extends, thus connecting the knob with the lever iii) can

for actuating the driver 65. One embodiment of p 'the invention having now been described in detail its mode of operation is explained as follows:

The implement is prepared for operation by swingingthe'gate 'on its pivot-pin 68 to open the forward end'of the magazine 4|. A supply of staples s,- preferably in stick form, is inserted into the magazine 4| by sliding themrearwardly against the action of the pusher 1|. The gate .55 is then swung to itsclosed "position to cooperate with 'the end of the rails 48 to form the throat 51'through which the staples s are driven.

The work w to be stapled is placed on the anvil 28 and manual pressure applied to the knob I88 to rock the stapling'arm 48 toward the base 2. The forward end of the magazine 4| first en-- gages the'workw to clamp it against the anvil '28 and continued pressure on the knob I88 causes "the lever 42- tomove relatively of the magazine.

Theactuating lever 61 for the staple driver 65, being connected to th operating lever 42 and knob I88 by the'pin I84,is rocked on its'pivotpin 68 to thereby actuate the driver to drive a "staple s fed'forwardly from the magazine 4|. "When the operating lever 42 is releasedthespring 69. acting between the actuating lever 61 and the stapling arm and base 2 cause the partsto "stapling arm 48 and the spring'16 acting between be returned to their-inoperative position illus- The spring 12 then acts on the pusher H to advance the staples in the magazin'e -'4I to again position the foremost staples in the "throat 51 beneath the staple-driver The 'Sshaped spring 32 tensioned between the stud-33 onfthe base 2 and the stud -26 on' th'e sliding anvil-28yieldingly holds the stud 26 in engagement with the tongue 30, See Fig/ B, to Inormally aline the rearvvanrl #s'et -of aunchergrooves 23 with the staple s beingfd riven The anvil 20 is initially adjusted to insure proper registry of'its clincher-grooves withthe stapledriver by bending the tongue 30 either forwardly or rearwardly. When a permanent stitch is desired the operator applies pressure to the knob I00 on the lever 42 forwardly of the pivot-pin N14. The knob I00 is thus rocked'in the pivotpin I04 to raise the control arm I06 above and out of engagement with the locking lever 86. The

locking lever 86, being under the influence of the spring 89 is then rocked on its pivot-pin 68 in a clockwise direction as viewed in Fig. 2 to hold its outwardly-projecting lateral lug 81 in raised position above the slide 80.

As the magazine 4| and slide 80 mounted thereon rock on the pivot-pin I2 toward the base 2 the lower end of the depending arm 84 on the slide 80 tends to move downwardly and rearwardly in an are about the pivot-pin l2. The

depending arm 84 on the slide 80 will thus be engaged with the upstanding flange 25 on the anvil 20, and due to the greater resistance of the spring 32 for holding'the anvil than the spring 89 for holding the slide, the latter will slide longitudinally of the stapling arm 40; Thus the applies manual pressure on the control knob use rearwardly of its pivot'which causes the knob and control arm I06 attached thereto to rock in a clockwise direction from the position shown in Fig, 1 to that in Fig. 3; The rearward free end of the control arm I06 will thus be engaged with the inwardly-projecting lateral lug 88 on the looking lever 86 to rock the latter in a counterclockwise direction about its pivot-pin 68 from the position illustrated in Fig.1 to that illustrated in Fig. 3 thereby causing its outwardly-projecting lug 31 to engage with the locking shoulder 85 on the slide '80. The slide 80 is then positively "locked to the magazine 4| so that it cannot move longitudinally thereof. During the rocking movement of the stapling arm 40 toward the base 2 the'depending arm 84 on the slide 8|] is moved downwardly and 'rearwardly into engagement with the upstanding flange 25 on the sliding an- 'vil 20 and consequently the longitudinal component of movement of the arm 84 is translated into longitudinal sliding movement of the anvil on the base 2. Thus, the anvil 20 is slid rearwardly as the stapling arm rocks toward the base with the S-shaped spring 32' yielding to permit such movement.

The separate sets of clincher-grooves 23 and 24 are spaced apart longitudinallyof the anvil 1 20 a distance equal to the longitudinal componentof ar'cuate movement of the lower end of the depending arm 84 on the slide 89 so that the forward set of clincher-grooves 24 are brought into alinement with the driven staple 8. When the stapling arm 40 is released the magazine 4| and operating lever 42 are returned to their in operative position in the manner as explained aboveand the S-shaped spring 32 slides the anvil 20 forwardly until the depending stud 26 engages the tongue 30 to aline the rearward set of clincher grooves 23 with the driven staple. Thus, when the. control knob Illll is tilted forwardly the anvil 20 is held in fixed position on the base 2 to aline the fastener being driven with the rearward set of clincher-grooves 23 and the slide moves longitudinally of the stapling arm 40; and when the control knob is tilted rearwardly the slide 80 is locked to the stapling arm 40 and the anvil 2|] is slid rearwardly on the base 2 to aline the forward set of clincher-grooves 24 with the driven staple. I In Figs. 10 to 12 a modified form of construction is illustrated as incorporating a locking element |||l on the fastener-applying arm adapted to lock the tiltable knob I00 in either of its two positions of adjustment. In this latter form of construction the knob Hill is of identical construction with. that illustrated in Figs. 1 to 9 and is mounted on the fastener-applying lever 42 in the sameway. The opening M3 in the top wall of the operating lever 42, however, is made longer and wider to receive the locking element H0. The' locking element H0 is in the form'of a plate having its central portion depressed to provide forward and rearward inclined cam-faces Ill and ||2and side flanges H3. An opening 4 is provided in the depressed central portion of the element |||l through which the depending ears I02 on the knob 10!) project. The depressed portion of'the locking plate Ill] extends into the opening H33 in the operating lever 42 to adapt the marginal-portion of theplate to seat on the top wall 95 of the lever; see Fig. 10. As illustrated in Fig. 11, finger-piecesv H5 project laterally from the locking plate I It] to adapt the lat ter to be gripped manually and slid forwardly or rearwardly.

With the locking element III] in the neutral position illustrated in Fig. 10 the knobv I06 may be tilted eitherlforwardly or rearwardly during the operation'of the implement to aline the staple being driven with either the forward or rear ward .set of clincher-grooves 23 or 24 on the anvil 20. If the operatordesires to continuously clinch each stap-leto form a temporary stitch the lock ing'element' I It is slid forwardly to the position illustrated in Fig. 12 by means of the. finger-pieces I I5. As the locking. element I ll] is slid forwardly its forward cam face III will engage the forward edge of the opening I03 in the top wall 95 of the lever 42 and rock the element to tilt the knob lllll rearwardly When the locking element is slid to its forward position itsbottom edge will seat on the top wall 95- to hold the-knob ||l|l in,its rearwardly tilted position. The slide 80 will be then permanently locked to the magazine 4| to cause the anvil 25] to be slid rearwardly on the base'2 each time thel-fastener-applying arm 40 is rocked toward the base 2' whereof to aline the staple being driven with the forward set of clinching grooves 24. Q a

If, on the other hand, the operator desires to continuously clinch each staple to form apermanent stitch the locking element I II) is slid rearwardly. and due to the engagement of its rearward cam -face l2 with the rearward edge of the opening H03 in the lever 42 the knob ill!) will be tilted forwardly and held in this position of adjustment. :Thus the slide 80 will be free to slide withrespec t to the magazine 4| and the staples being driven will be operated upon by th rearward set of clinching grooves 23.

It will be observed from theforegoing description that the present invention provides for selective'operation of theimplement to clinch the fasteners by different methods; It will be observed also that the selective adjusting means is controlled from the fastener-applying means and operated by theforce applied to drive the fasteners; Further, it will be observed that the implement is of relatively simple construction and positive in its operation to selectively control the type of stitch to be formed.

Whilethe device is herein illustrated and describedasembodied ina; preferred form of construction, it is to be understood that modifications maybe made in the structure and arrangement of its parts Without departing from the spirit or scopeof the invention.
